Solutions of nonlocal cosmological equations Available to Purchase

A general class of gravitational models driven by a nonlocal scalar field with a linear or quadratic potential is considered. The Ostrogradski representation for nonlocal gravitational models and the way of its localization are proposed. We study the action with an arbitrary analytic function $F(□g),$ which has both simple and double roots. The way of localization allows to find solutions of nonlocal Einstein equations.
